"We've had mixed comments, you know, from people telling us that we should have kept it, that we made a mistake, telling us no one would ever have found out," he said.

The pair happened upon the money on Monday afternoon. They were driving along busy Coburg Road in Eugene when they saw a bank deposit bag in the road. They stopped, opened it up and saw a thick wad of hundred-dollar bills inside, Ryan said.

"We both kind of… we were speechless for about three, four minutes, our hearts racing, but we both figured that someone had probably lost it," he said.

Their father, Erik, lived nearby, so they took the money to him because they thought he would know what to do.

Erik Moi said he was in the shower when his children stopped by. "I heard them in the living room screaming 'Dad, we found $13,000,'" he said.

In addition to the cash, the bag contained a slip indicating the total amount of the cash as well as checks made out to Reliable Credit Association, an Oregon-based consumer finance company. Reliable has an office not far from Erik Moi's house, and he happened to know the manager, so he offered to take the money there that afternoon.

He recalled going in to see the manager.

"I said 'Kyle, you missing something?' And I handed him the bag and he just kind of turned white," Erik Moi recalled.

Reliable presented the siblings each with a $200 Visa gift card on Wednesday, Ryan Moi said, adding that he and his sister have both received job offers. Someone who read about what they had done bought Katie Moi, 21, a new MacBook laptop to replace the one that was stolen from her.
